Executive Summary ENVIRONMENT IMPACT ASSESSMENT REPORT FOR IMPROVING THE CAPACITY UTILIZATION OF OR 1AND OR2 BERTHS AT VISAKHAPATANAM PORT TRUST Prepared for VISAKHAPATNAM PORT TRUST Prepared by Environmental Consultancy and Laboratory NABET/EIA/1417/RA010 September 2017 1.0 PROJECT DESCRIPTION The Visakhapatnam Port, one among the thirteen Major Ports of India, is an all weather natural Port and the fastest growing maritime gateway to the peninsular India. The Port is located on the East Coast of India in between Chennai and Kolkata at a latitude of 17 0 42' 00'' North and longitude of 830 23' 00'' East Visakhapatnam Port, a premier port of our country situated in the state of Andhra Pradesh India has been handling large volumes of cargoes and has been in the first position among all the major port of our country successively during the year’s 2001 to 2007. The Port comprises of Inner harbour (a natural harbour within Mehadri Gedda River), Outer Harbour (an artificial harbour at the mouth of the Mehadri Gedda River) and Fishing Harbour (an artificial harbour catering exclusively to fishing vessels).Outer Harbour with a water spread of 200 hectares (ha) has 6 berths is capable of handling ships up to 200,000 DWT and draft up to 18.1 meters. Inner Harbour, with a water spread of 100 ha has 18 berths capable of accommodating fully laden Panamax vessels with draft up to 14.5 meters, with tide advantage. At present Inner Harbour is capable of handling vessels of up to 12.5 m draft. In order to meet the requirements of cargo carriers and increase the cargo handling capacity of Visakhapatnam Port, the approach channel and turning circle of Inner Harbour are being deepened to cater to fully loaded Panamax Vessels with a draft of up to 14.0 m. The existing OR I – OR II berths, located in the Western part of Inner Harbour, were constructed in 1957 and are of monolithic construction. The available draft at these berths is 10.5 m at present. They have outlived their useful life (fixed as 50 years by the Ministry of Shipping, Govt. of India). It is proposed to construct a additional oil berth of length 180 m in between fertilizer berth and OR-II. The existing berths will be demolished and reconstruction of new OR-I and OR-II with facilities.Construction of protection wall with length of 30m shall be constructed at end of OR- I berth on seas side. Widening of western arm channel by 12 m along the alignment of the proposed new development.Increase the dredge depth from (-)10.70m to (-) 16.10m. The project will be implemented in two phases, each phase The construction of additional berth between the OR-II and fertilizer berth shall be executed in stage 1, After completion of the new additional berth, the dismantling and reconstruction of OR-I commences with additional berth length of 60 m which is followed by OR-II. OR-II will be decommissioned and dismantled after completion of additional berth and new OR-I. The new development will have a dredge depth of -16.1 m to handle higher capacity vessels of upto 85,000 DWT with maximum draft of -14.5m.The proposed project does not envisage any land acquisition. The existing berths have hardly any vegetation and hence the proposed project shall not involve any tree felling.At present the existing berths are handling Naphtha,MS,SRO,AIT,HSD,LDO,FO,LSHS,MS,HSD. Proposal The construction of additional berth between the OR-II and fertilizer berth shall be executed in stage 1 of development plan as desired by VPT management. After completion of the new additional berth, the dismantling and reconstruction of OR-I commences with additional berth length of 60 m which is followed by OR-II. OR-II will be decommissioned and dismantled after completion of additional berth and new OR-I. Protection wall with length of 30m shall be constructed at end of OR-I berth on east side. The proposed development is planned to operate one handymax and one Panamax vessel as per the suggestion of Joint Director. So the length of additional berth is required as 180m. Overall length of proposed berth is 606m. [OR-I + Extension of OR-I + OR-II + Additional berth (ie.183+60+183+180=606m)] The new development will have a dredge depth of -16.1 m to handle higher capacity vessels of upto 85,000 DWT with maximum draft of -14.5m.

Wastes discharged from ships will be handed over to the port’s licensed contractors who have appropriate waste handling and disposal facilities Proposed Rs.193.3 Crores Investment 2.0 DESCRIPTION OF THE ENVIRONMENT The study area lies in tropical region where climate is characterised by very hotsummers and mild winters.During the Summer Season months the predominant wind directions are South- west, south and West, prevailing for 49.2%, 20.1%, 10% and of the time respectively whereas Calm prevailed 8.3% of the time. Baseline environmental data generation was carried out during full summer season, 2017 covering March, April and May. Primary data was also augmented by data from secondary sources. The baseline environmental data generation covered micro-meteorology, land use, air quality, water quality, noise levels, soil quality, ecology, traffic density and socio-economic environment. Information on physical oceanographic conditions, climate and population were collected from secondary sources. Micro-Meteorology The mean annual rainfall is 968.8 mm (average of 52.0 rainy days per year). The South-west monsoon lasts from June to October and the area gets ~78.5% during this period. October is wettest month (mean monthly rainfall of 204.3 mm; 8.7 rainy days), followed by September (174.8 mm, 9.9 rainy days) and August (141.2 mm; 9.3 rainy days). The humidity is comparatively high and fairly uniform throughout the year. The mean daily relative humidity over a year is about 76% at 0800 hrs and 72% at 1700 hrs. The highest recorded value is81% and lowest recorded value is 64%. The predominant direction of wind is south-west or north-east depending on the monsoon season. The south-west monsoon winds are relatively stronger than the north-east winds. The annual mean maximum temperature is 30°C and the annual mean minimum temperature is 24.3°C. Land Use Mapping of land use and land cover was carried out for the proposed site using remote sensing satellite data. LANDSAT-8 cloud free data has been used for land use / land cover of the study area (10 km radius from the proposed site). The overall land use of 10 km radius area shows that water bodies dominate with the Bay of Bengal which constituting 35.3% of the total. Visakhapatnam is a highly populated place hence the built-up land occupies 19.83% in the study region. Other land uses include open scrub (18.45%), vegetation (12.13%), open land (9.27%), Current Fallow (4.43%), sandy region and rocky region (0.36% and 0.23%) respectively. Air Quality Ambient air quality was monitored at Ten locations (Old Post Office, Fishing Harbour,Poorna Market, MVP Colony, Kailaspuram, Kakaninagar, Mindi,Sriharipuram,pedagantyada and project site). Samples were collected for Particulate Matter (PM10& PM2.5), Sulphur-di-oxide (SO2) and Oxides of Nitrogen (NOx) 24 hours continuously twice a week for twelve weeks at each location. Samples of Carbon Monoxide (CO) collected for at each location. The results were compared with the National Ambient Air Quality Standards, 2009 for “Industrial, Residential, Rural and Other Areas”. All the values are within norms . Water Quality Water quality monitoring was carried out at 9 locations in which Surface water (3 locations Air port channel, Dockyard canal, Mudasarlova Lake) and ground water covered (6 locations Old post office, poorna market, Port staff colony, Kailasapuram, Kakani nagar and Sriharipuram). The results of surface and ground water analysis were compared with the standards for drinking water [IS:10500 (as amended in 2012)]. Noise levels Ambient noise levels were monitored for 24 hours at 10 locations (10 locations where ambient air quality monitoring was carried out). Day time noise levels at the locations where ambient air quality had also been monitored, were within the norms for Industrial Areas.It is to be noted that Visakhapatnam is a major city with a lot of commercial and industrial activities and people are active from early morning to late night Work zone noise was monitored at three locations at hourly intervals for eight hours.
